SONY	KX2501	Lines across screen top and bottom, normal (support wire)	When viewing monitor with no video there are faint whitevertical lines across the screen. this appears to be horiz. pulsespossibly from the scan derived b+ voltages. customer noticed these whilerecording with camera and became very critical. he insist
SONY	KV8000	Shut down	Set works fine for an hour or so then goes dead. will comeback on and repeat.
SONY	KV2650R	No operation, replaced d021	Unit cannot be turned off except by master switch, no functionon any mode, i.e. power on/off volume up/down, channel up/down, pictureup/down etc. voltage on pin 2 on ic001 was high (4.8v). found d021leaky (500k).
SONY	KV2648R	Snow picture, r557 changed value	The picture exhibited light snow on all channels all thetime the unit was on. after 5 to 10 minute warm up the picture shrankabout 2 inches vertically.

SONY	KV1947R	Poor remote operation, replaced ic101	Intermittent (2-3 weeks) operation in remote and push-buttonfailure.
SONY	KV1947R	No vhf, replace ic002	Set had uhf operation but no vhf operation. no vc was presenton tuner. all switching voltages were correct and verified against akv-1948r. applying external dc to vc line tuned all stations.
SONY	KX1901	Lighter raster on the top	These units had a light area across the top of the screen.the first 12 to 15 scan lines after vertical blanking were lighter thanthe remainder of the raster. it looks like the units had a poor blacklevel just after vert. blanking. also these units have
SONY	KV1222R	Incorrect mechanical operation	The door assy will not stay closed due to the fact that thedoor retainer which is a plastic material, will not engage the catch onthe door securely in order to keep the door closed. this condition isprevalent on at least a dozen sets or more at the acco
